Never used FW tank, need to sanitize for use next week, how?

I never got into drinking or cooking from the fresh water tanks... Being a fresh ground and brewed bean coffee drinker we found out you have to have the same brand of bottled water to get the taste you want so we always have a couple of gallons of bottled water with us at all time anyway.

We usually just use our fresh water tank for general cleaning, showers, and such....

Just us - nothing unsafe about consumption from the fresh water tanks...
